I found 2.1 on my Sprint Pre to be too slow, so I built a Franken PreČ. On a Sprint Pre, 1.4.5 runs very well, esp over-clocked to 800 or 1000 MHz.

Does 1.4.5 have application support still? Patches and such on homebrew are still available? I read around on a good maps app, does Navit work on 1.4.5 or only 2.1? I know the newer apps may not be available since they are built for 2.1, anything important I may miss out on?

Is the Frankepre worth building on the Pre 2? They are pretty cheap these days on Ebay.
